From: Luis R. Rodriguez <lrodriguez@atheros.com>
commit 8b685ba9de803f210936400612a32a2003f47cd3 upstream.
AMDPDU actions poke hardware for TX operation, as such we want to turn hardware on for these actions. AMDPU RX operations do not require hardware on as nothing is done in hardware for those actions. Without this we cannot guarantee hardware has been programmed correctly for each AMPDU TX action.
